Bulls' forward Luol Deng may be off the British National Team because of an issue with the insurance on his newly signed contract with Chicago, according to a report by the website Basketball 24/7.

According to the report, the NBA's insurance company has refused to completely insure Deng because of an old back injury.

Under an arrangement with world-governing body FIBA, the NBA is obliged to release any player who wishes to play for his national team but only if insurance requirements are totally met.
